TOOL-HANDLE.

Application filed. January 19, 1912.

To all whom t may concern Be it known that l, Jol-IN L. Oseoon, citizen of the United States, residing at Buf. falo,` in the county of Erie and State ofiy New York, have invented a new and useful Improvementk in Tool-Handles, of which the following is a specification.

This invention relates more particularly to improvements in wooden tool handles oli the sort used for files and other hand tools having a tapering tang which is driven into an axial hole in the end of the handle fori securing the handle on the tool. Since the handle is held on the tool by friction only,

15, it works loose from time to time in the use of the tool and the tang has to be driven farther and farther into the handle to prop-. erly secure the tool, with the ultimate ree. sult that a great many handles are split and destroyed unless they are specially rein-y forced. Patent No. 857,894, granted to me June 25, 1907, discloses a handle of this kind having a metal tube reinforcement eX- tending into it from the tool-attaching end around the tang hole for preventing the handle from splitting. This construction hask been found by extended use over a considerable period of time to make the handles practically indestructible. However, the strengthening tube must be comparatively thin and in order, therefore, toy secure the strength necessary to withstand the excessive outward strain resulting from. the expansion of the wood caused by driving in the wedge shaped tangs, the reinforcing tubes have to be seamless, drawn from high grade stock, or they must be turned down to the proper thickness from heavier tubes. The tubes are, therefore, expensive to produce and add materially to the cost of the handles.

The object of this invention is to provide an improved reinforcement for preventing` the splitt-ing of' the handles whichl affords the advantages of the tubes employed in said patented handle, but which makes the handles stronger and more durable and, at the same time, is less expensive than said tubes. rlhis is accomplished by inserting into the body of the handle between the surface thereof and the tang hole, in place of the metal tube before employed, a reinforcement consisting of one or more coils of line, strong wire. Since the wire has great tensile strength in the direction in which it is wound, or circumferentially, the wooden core within the coils and into which the tang of Specication of Letters Patent.

the tool is driven is surrounded by a reinforcement or binder which has ample 4strength to resist the expansion of the in- -the outwardv pressure, and` if the strain is ltoo great, it will split the tube. But, as the convoluti'ons of the wire coils are relatively movable, one portion of the coil is adapted to yield slightly relative to another portion under the expansion of the inclosed wooden co-re, so that it is practically impossible in an;7 ordinary use of the handles to break the wire coil and split the handle.

In the accompanyingr drawings: Figure l isa side elevation and Fig. 2 is a, longitudinal section of a tool handle embodying the Fig. 3 is a fragmentary view thereof showing the strengthening coil in elevation. Fig. 4 is a cross. section thereof inl line 4 4, Fig. 2, and Fig. 5 is an end elevation. thereof; Fig. 6 is a longitudinal Vsection of a slightly modified construction.

Like reference charactersrefer to like parts in the several figures.

Referring first to the handle shown in Figs. 1 to5. A represents the handle which may be ofany shape suitable for the handles zof files and other hand tools having a tang adapted to be driven into the handle for securing the handle thereon. Wooden handles rarel usually demanded for hand tools, and

the handle is, therefore, preferablyv made of wood., but it could be made of other material.

An axial hole a is provided in the inner end of the handle to receive the tang of the tool and? this end ofthe handle is preferably reduced to form the usual neck which is sury rounded and protected by the usual ferrule c.

dition to these usual requirements, the hanwell into the handle and is preferably composed of two or more wire coils. The handle is provided in any suitable manner with a narrow annular recess into which the coils are forced and in which they are tightly held in place with spaces CZ between the adjacent coils. These spaces allow the inclosed core of wood to expand slightly between the coils under the outward pressure caused by driving the tang into the handle, and permit the tang to be driven well into the handle and vfirmly seated, but the coils prevent the tang from splitting the handle. The coils preferably extend into the handle to or beyond the point to which the tang or-the tool extends when it is driven into the handle to the limit, so that the tang can not possibly expand and cleave the handle beyond the coils. l

The iianged outer end of the ferrule c covers and hides the outer end of the coil recess and prevents theA possibility of the outer end of the coil from protruding from the recess.

ln the handle shown in Fig. 6, the rein* forcement consists of a single continuous wir'e coil D', instead of the several shorter coils, as in the construction iirst described. This ligure also shows a similar reinforcing coil E inserted into the other, or outer, end

of the handle for preventing the splitting thereof. This coil can be used or not as preferred, and a similar coll can be used in the outer end of the handle shown inl Figs. 1-5, if desired.

The handle provided with the describedV reinforcing device has all of the advantages and desirable features of the ordinary ferrule-tipped wooden handles.V It has the same long wooden grip or hand-hold extending from end to end of the handle,

except for the portion covered by t-he ferrule; the wooden socket into which the tang of the tool is driven and retained; and it may have the same appearance. In addle is rendered practically indestructible by the coiled wire reinforcement 0r binder. The wlre coil reinforcement or binder de- 'as when a non-yielding tube isused.

wire, said coils being separated by interless expensive than the strengthening tube.

referred to, has the further advantage that it permits a slight expansion of the inclosed wooden core when the tang is driven into it, so that the core is not compressed so lard onsequently the tang can be driven into the handle more readily andthe core retains some of its elasticity and therefore more irmly grips and holds the tang.

I claim as my invention:

Y 1. A. wooden tool handle having a hole in one end to receive the tang of a tool, said handle having a narrow annular recess formed therein around said hole and between the walls of the same and the outer surface of the handle, and a coiled wirereinforcement in said recess, said reinforce-V ment extending at least approximately from end to-end of said hole, substantially as described. Y

2. A wooden toolhandle having a hole in one end to receive the tang of a tool, said handle having a narrow annular recess f formedtherein around said khole and'between the walls of the same and the outer surface of the handle, and a plurality of reinforcing members inserted in said recess each of which comprises a helical coil of vening spaces, substantially as described.

3. A wooden tool handle having'a holeV in one end to receive the tang of a tool, said handle having a narrow annular recess formed therein around said hole and between the walls of the same andthe outer surface of the handle, a coiled wire reinforcement in said recess, and a ferrule on the end portion of the handle, said fer` rule extending over and closing the end of said recess, substantially as described.
